What is Amazon S3 Files?

It's a mountable file system view of your S3 bucket. POSIX full—ls, grep, edit—all sync back to S3 without copying data. Works on existing buckets, NFSv4.1 protocol.

How does S3 Files integrate with AI pipelines?

Mount to EKS/EC2. Agents read/write hierarchically. Small files cache fast; large stream from S3. Ends wrapper latency for pandas, Dask, etc.

Will S3 Files replace EFS for everyone?

Not fully—EFS for pure shared FS. But for S3-heavy workloads? Yes, slashes costs and sync ops. Test in your VPC; GA now.
